Given numbers are 221,909,145,340

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 221,909,145,340 is 116515620.

Find LCM of 221,909,145,340 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

5 x 17 x 13 x 909 x 29 x 4 = 116515620

Therefore, the lowest common multiple of 221,909,145,340 is 116515620.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

221 x 909 x 145 x 340 = 9903827700

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

221 : 1, 13, 17, 221

909 : 1, 3, 9, 101, 303, 909

145 : 1, 5, 29, 145

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,909,145,340, is 1.

Now, the common factors can be found like this.

221:13x 17

909:3x 3x 101

145:5x 29

340:2x 2x 5x 17

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

5x 17 = 85

Therefore, the value for common factors is 85.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 9903827700/(1x85)

LCM = 9903827700/85

LCM = 116515620

Thus, we can understand that the LCM of 221,909,145,340 is 116515620.
